<p>An abrasive machine (10) comprises a rotatably driven tool (35), chucking equipment (27) for holding the work piece and feeding means (20, 21) for effecting relative displacement between the work piece (28) and the rotatably driven tool (35). The machine (10) further comprises: a tubular cylindrical housing (13); a shaft (17) provided with a recess; a rotatable outer casing (15) peripherally enclosing the housing (13); a lid member (30) connected to the casing (15), and extending radially over a first end of said tubular cylindrical housing (13) such that an inner surface (33) of said lid member faces said first end of said housing, wherein said rotatably driven tool (35) comprises abrasive material carried on said inner surface (33) of said lid member (30), and in that said shaft (17) is arranged such that when said shaft executes an angular displacement, said work piece (28) held by said chucking equipment (27) is caused to approach and contact said abrasive material.</p> |
